Fault code P242F indicates that the diesel particulate filter, also known as the DPF, is excessively saturated or clogged. This fault is common in diesel vehicles and can lead to loss of power, increased fuel consumption and an illuminated engine warning light.
With P242F Peugeot and P242F Renault, the fault is usually caused by a failed DPF regeneration or a defective pressure sensor that incorrectly reads the saturation level.
Driving for a long time with this fault can damage the DPF or the engine management system.
To solve P242F with an additive, you can use a product such as Total Care Diesel or Lindemann DPF Cleaner.
These additives help clean the diesel particulate filter by increasing the combustion temperature and burning off accumulated soot.
If the problem continues, professional DPF cleaning or replacement is necessary. Driving regularly at higher revs and using high-quality fuel can help prevent the DPF from becoming clogged again.
